Clutch Switch: Adjustments

Clutch Pedal, Clutch Pedal Position Switch, and Clutch Interlock Switch Adjustment

NOTE:

- For a cruise control problem, check the clutch pedal position switch Clutch Pedal Position Switch Test.
- For a clutch interlock operation problem, check the clutch interlock switch Clutch Interlock Switch Test.
- Remove the driver's floor mat before adjusting the clutch pedal.
- If there is no clearance between the master cylinder piston and the push rod, the release bearing will be held against the diaphragm spring, which can result in clutch slippage or other clutch problems.
- Without cruise control: The adjusting bolt is substituted as clutch pedal position switch. The clutch pedal height adjustment is same procedure as with the clutch pedal position switch.
